Abstract
A compact dual beam generator was realized by exploiting an integrated optic beam aligner accompanied by an aspheric lens, to deliver collinear infrared (IR) and visible collimated beams. The aligner entails straight and bent silica waveguides for IR and visible channels, respectively, which are hybrid integrated with laser diodes at λ=905 and 605 nm. The guided-wave aligner is fixed to IR and visible laser diodes via active power monitoring, then combined with a lens to construct a 35-mm-long beam generator. The produced IR and visible collimated beams feature profiles with a divergence of ∼0.1° and an angular alignment of 0.13°.
